Extended Text: Scientists using observations from NASA's Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite detected flashes of gamma ray energy in Earth's upper atmosphere in greater detail than ever before. RHESSI is part of NASA’s Sun-Earth Connection program. It was designed to study X-rays and gamma rays from solar flares. However, RHESSI's detectors pick up gamma rays from a variety of sources.
